Stops Gas Leaks & Eliminates Sluggish Bolt Performance
Single spiral of spring steel loops around the bolt three times and
leaves no path for gas leakage. Replaces conventional three-piece
“piston ring”-style sets that can accidentally line up, causing a
major leak from the gas expansion chamber in the carrier.
